JavaScript was the bane of the web development industry during the early days of the browser-rendered Internet. It now powers hugely impactful libraries such as jQuery, and JavaScript-rendered content is even indexed by many search engines.

Not only is JavaScript now more prevalent than ever in frontend architecture, but it has become a server-side language as well, thanks to the Node.js runtime. We have also seen the proliferation of document-oriented databases, such as MongoDB, which store and return JSON data. With JavaScript present throughout the development stack, the door is now open for JavaScript developers to become full-stack developers without the need to learn a traditional server-side language. Given the right tools and know-how, any JavaScript developer can create single page applications comprised entirely of the language they know best.
